I've got the factory dual-cat setup on my camaro, and I'd like to add some aftermarket headers to my car. I know of some y-pipes that are made for the dual-cat setup but they're serious bank..I'm on a bit of a budget and was just curious of what my options are?

If I need to fork over some dough to get a good flowing y-pipe then I guess I better start collecting my cans now lol.

 

yup, save your money and a nice get stainless setup. In the long run you'll be glad you did!

 

Haha alright then cool, I guess I'll just do that then. Can anyone recommend some good headers with the air tube that are fairly well priced as well?

 

You will have to cut the ends off of your stock ypipe close to where they bolt up to the stock exhaust manifolds and either have a shop fabricate the new ends for you to bolt up to your headers or buy the ypipe that matches from the same header manufacturer.

 

Ok for example I go with the method where I re-use my stock piping and get them modified, wouldn't that defeat the purpose of the headers? Or is the stock piping on a dual-cat car have a decent enough diameter to allow good flow?

 

Your fine if you have the dual ypipe (N10)option. Comparable to a 3" single pipe. The dual ypipe added something like 10hp over the single. What i did was install the headers myself and had the stock dual ypipe modified. Cost me $92 to have the welding done.

 

Modified how so? To fit the 3" collector on the headers? If so then $100 ain't too bad. Good to know that the dual-cat piping was good for 10hp over the single cat cars

And yeah I believe there's only one way the dual-cat car pipes work, 2 seperate pipes come down off of the collectors, both go into 2 seperate cats and then after the cats Y into the intermediate pipe correct?

I refuse to call the piping after the headers y pipes because no where in the piping does it y LOL

If you choose to keep the dual ypipe setup, it will be a lot easier for you to just cut your dual ypipes off at about 6 inches from where they connect to the exhaust manifolds, remove your exhaust manifolds, install your headers, drive to the shop (don't get a ticket for noise) and then have a shop fabricate the rest for you

 

Gotcha, cool well I appreciate your input on my little dilemma here haha. Puts my mind a bit more at ease about the whole thing when the time comes to put some headers in!
